Doubt with declaring local variables as satic

[Supriya Nimakuri]

Which option most fully describes will happen when you attempt to compile and run the following code..

The output is given as option 4:..why cant be the output be option 2..since i has not initialized and used here..

public class MyAr{
public static void main(String argv[]) {
MyAr m = new MyAr();
m.amethod();
}
public void amethod(){
static int i;
System.out.println(i);
}
}

1) Compilation and output of the value 0
2) Compile time error because i has not been initialized
3) Compilation and output of null
4) Compile time error

You are correct in that i has not been initialized. However, the more important issue is the use of the static keyword.

Inside of an instance method, a static modifier makes no sense at all. Static variables must be fields of the class.

First appropriate declaration; then comes initialization.

There is only one modifier can be used by local variables that is final modifier.
